Place vqfx-20.2R1.10-re-qemu.qcow2 into your local GNS3/images/QEMU/ directory. Follow the GUI wizard to link the RE and PFE images.

Both components communicate over an internal connection. They do not function as a network device unless they are properly linked together. Step-by-Step EVE-NG Deployment

: Indicates that this image is the Routing Engine (RE) . The vQFX architecture requires two separate virtual machines to function: the RE (controls the plane) and the PFE (Packet Forwarding Engine, handles the data plane).

For QCOW2, virtio-blk offers lower latency, while virtio-scsi enables SCSI command queuing. In top , look at wa :

Mastering the Juniper vQFX: A Deep Dive into vqfx202r110reqemuqcow2

Upload your raw image file into this directory and rename it to match the recognized virtual hard drive standard:

The vQFX is a virtualized version of the physical Juniper QFX10000 series data center switch. It requires two separate virtual machines to function as a single device:

The is a vital asset for any serious network architect. It provides a high-fidelity environment to master Junos without the five-figure price tag of physical QFX hardware. By pairing this RE image with a stable PFE, you can simulate almost any modern data center scenario. Place vqfx-20

Before we spin up any virtual machines, we need to understand exactly what "vQFX" is and why the specific version 20.2R1.10 matters.

Unlike older versions, 20.2R1.10 supports advanced data center protocols. If you are building a Spine-and-Leaf architecture in a lab, this image handles the control plane requirements for VXLAN overlays and BGP underlays flawlessly.

and navigate to the QEMU directory:

This is the VM represented by our keyword. It runs the full Junos OS control plane. When you SSH into the vQFX, you are logging into the RE. It handles: They do not function as a network device

: This usually indicates that the PFE is not properly connected. Verify the RE and PFE are connected via their em1 interfaces and that the RE is using the virtio-net-pci driver.
